5 Preface أُولٰئِكَ عَلىٰ هُدًى مِن رَبِّهِم ۖ وَأُولٰئِكَ هُمُ المُفلِحونَYusuf AliThey are on (true) guidance, from their Lord, and it is these who will prosper1.Prosperity must be taken as referring to all the kinds of bounty which we discussed in the note to 2:3 above. The right use of one kind leads to an increase in that and other kinds, and that is prosperity.
